Separately, the same script collects the output of `id` and `hostname`, base64-encodes the result, and issues an HTTPS GET to jasabersama.id/portfolio-data.php with a hardcoded key parameter, providing the operator of that host a per-install beacon carrying installer identity. Because the dropper logic is duplicated in index.js, any consumer that does `require('@years18/n8n-nodes-utils-helper-n')` re-triggers the fetch, extraction, pip install, DDoS launcher, and beacon in addition to the automatic postinstall execution. The advertised package name imitates the n8n community-node namespace; the shipped code has no relation to an n8n node.\n","affected":[{"package":{"ecosystem":"npm","name":"@years18/n8n-nodes-utils-helper-n"},"versions":["1.0.0"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"callback.js","sha256":"939b22deea396f3518d6d974069b37918201181f7ce418fdac8cf4ad161f7f6c","tlsh":"8f4198b61252a538403363586f2bdd66d66fb10784d8bac8f64d43730f129386d5b76c"},{"path":"index.js","sha256":"939b22deea396f3518d6d974069b37918201181f7ce418fdac8cf4ad161f7f6c","tlsh":"8f4198b61252a538403363586f2bdd66d66fb10784d8bac8f64d43730f129386d5b76c"}],"package_integrity":[{"filename":"n8n-nodes-utils-helper-n-1.0.0.tgz","hashes":{"sha1":"5a93b29f8b929a6e2fd73201c9639b3ee6994ccb","sha512_sri":"sha512-mcm+VuecMgxY3tCJXqlJq4/pZRNMwHOgvprrMjvWfr582JoSdc4fqEgvkNdatXCAa4LwFrsIgOX5HMZIPrqIAw=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@years18/n8n-nodes-utils-helper-n/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017400","import_time":"2026-08-12T12:24:09.91560672Z","modified_time":"2026-08-12T12:16:21Z","sha256":"f747eb82d36d203eb7d0e49df70c41f696f8909284c48a4a8d6a7e785e1b5f98","source":"amazon-inspector","versions":["1.0.0"]}]}}
